DESCRIPTION
The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
Applied Micro Circuits Corporation (AMCC), the premier supplier of single chip solutions, has developed the S5335 to solve the problem of interfacing applications to the PCI Local bus while offering support for newer PCI chipsets and operating systems. The S5335 is a powerful and flexible PCI controller supporting several levels of interface sophistication. At the lowest level, it can serve simply as a PCI bus Target with modest transfer requirements. For high-performance applications, the S5335 can become a Bus Master to attain the PCI Local bus peak transfer capability of 132 MBytes/sec. The S5335 was designed for 3.3V environment but its inputs/outputs are tolerant to 5V signaling.

Description
The ZXGD3101 is intended to drive MOSFETS configured as ideal diode replacements. The device is comprised of a differential amplifier detector stage and high current driver. The detector monitors the reverse voltage of the MOSFET such that if body diode conduction occurs a positive voltage is applied to the MOSFET's Gate pin.
Once the positive voltage is applied to the Gate the MOSFET switches on allowing reverse current flow. The detectors' output voltage is then proportional to the MOSFET Drain-Source reverse voltage drop and this is applied to the Gate via the driver. This action provides a rapid turn off as current decays.

Features
• Turn-off propagation delay 15ns and turnoff time 20ns
• Suitable for Discontinuous Mode (DCM), Critical Conduction Mode (CrCM) and Continuous mode(CCM) operation
• Compliant with Energy Star V2.0 and European Code of Conduct V3
• Low component count
• Halogen free
• 5-15V VCC range

Applications
Flyback converters in:
• Adaptors
• LCD monitors
• Server PSU’s
• Set top boxes

Description
Lattice’s Power Manager II ispPAC-POWR1014/A is general-purpose power-supply monitor and sequence controller, incorporating both in-system programmable logic and in-system programmable analog functions implemented in non-volatile E2CMOS® technology. The
ispPAC-POWR1014/A device provides 10 independent analog input channels to monitor up to 10 power supply test points. Each of these input channels has two independently programmable comparators to support both high/low and in-bounds/out-of-bounds (window-compare)
monitor functions. Four general-purpose digital inputs are also provided for miscellaneous control functions.
The ispPAC-POWR1014/A provides 14 open-drain digital outputs that can be used for controlling DC-DC converters, low-drop-out regulators (LDOs) and optocouplers, as well as for supervisory and general-purpose logic interface functions. Two of these outputs HVOUT1-HVOUT2) may be configured as high-voltage MOSFET drivers. In high-voltage mode these outputs can provide up to 10V for driving the gates of n-channel MOSFETs so that they can be used as high-side power switches controlling the supplies with a programmable ramp rate for both ramp up and ramp down.
The ispPAC-POWR1014/A incorporates a 24-macrocell CPLD that can be used to implement complex state machine sequencing for the control of multiple power supplies as well as combinatorial logic functions. The status of all of the comparators on the analog input channels as well as the general purpose digital inputs are used as inputs by the CPLD array, and all digital outputs may be controlled by the CPLD. Four independently programmable timers can create delays and time-outs ranging from 32μs to 2 seconds. The CPLD is programmed using Logi-Builder™, an easy-to-learn language integrated into the PAC-Designer® software. Control sequences are written to monitor the status of any of the analog input channel comparators or the digital inputs.
The on-chip 10-bit A/D converter is used to monitor the VMON voltage through the I2C bus of the ispPACPOWR1014A device.
The I2C bus/SMBus interface allows an external microcontroller to measure the voltages connected to the VMON inputs, read back the status of each of the VMON comparator and PLD outputs, control logic signals IN2 to IN4 and control the output pins (ispPAC-POWR1014A only).

Features
*Monitor and Control Multiple Power Supplies
- Simultaneously monitors up to 10 power supplies
- Provides up to 14 output control signals
- Programmable digital and analog circuitry
